Therapeutic use of enilconazole in broiler chicks with aspergillosis

: The course of a spontaneous outbreak of aspergillosis in a broiler flock was studied. Up to the 10th day of life the total mortality was 8%. Surviving broiler had an average body weight of 141 g on the 7th day of life, in contrast to the normal body weight of 150 g per bird. Aspergillosis was diagnosed in another three broiler flocks as well in an early stage of infection. Treatment with Enilconazole (Clinafarm Spray, Janssen, Neuss) in these flocks at a single time via spray in a dosage of 1.5 g enilconazole per 10 m2 housing ground obviously reduced mortality from the second day on after treatment. The average body weight of 7-day-old broiler was in a normal range. The success of the treatment depends on an early diagnosis and immediate start of the therapy. The source of infection (hatchery, transport, litter etc.) should be discovered and eliminated to prevent flocks from further infections.
